Chapter 240: Chapter 240

An hour later, Lu Chuan had arrived at the cold storage.

"Lu, this is the place, take a look."

There was a hint of excitement in Zhang Xiao’s grave expression.

Just an hour ago, as Zhang Xiao was about to leave the cold storage, he inadvertently glanced at the support leg of the shelf against the wall.

He found a brown scar on the side of the support leg.

The front of the scar was normal, but on the side next to the wall, there were some marks.

From the front, this brown stain couldn’t be noticed.

Zhang Xiao discovered it because his position was parallel to the shelf, and the angle of the light just allowed him to notice the scar there.

Then, Zhang Xiao carefully examined it but was still not sure if it was caused by what he suspected.

So Zhang Xiao called the crime scene investigation team immediately.

Lu Chuan crouched beside the shelf, opened the crime scene investigation kit, and took out the LSK fluorescent illumination lamp.

As the light shone, the ground, wall, and shelves, initially colorless, were covered with dirt-brown marks.

Zhang Xiao was initially uncertain, but seeing the large areas of dirt-brown traces under the fluorescent lamp finally confirmed his discovery was indeed bloodstains!

However, someone had deliberately cleaned these bloodstains, leaving nothing visible on the surface.

But while bloodstains can be wiped away, hemoglobin in the blood is hard to eliminate completely.

Proteins in blood are difficult to wash clean with water, even if they seem gone from the surface, residues would still be present.

And such proteins have a strong reflection to fluorescence, appearing dirt-brown under the fluorescence.

Lu Chuan’s study of bloodstains was evidently more in-depth than Zhang Xiao’s.

Fluorescence can reveal the presence of bloodstains, but it cannot prove whether the blood is human.

Any animal blood traces will reflect under fluorescence.

"I’ll take some residue back for analysis, should have results in about half an hour."

Lu Chuan had just heard from Zhang Xiao that this cold storage was leased by a fruit trader.

Normally used to store some hard-to-preserve fruits.

If that’s the case, there shouldn’t be bloodstains here.

So, how did these bloodstains come about?

More importantly, Zhang Xiao checked these cold storages because Lu Chuan discovered that the body might have been refrigerated.

"All right, let’s split up. I’ll report to Group Leader Ren, see where Zhao Wenjun runs!"

Zhao Wenjun is the owner who leased the cold storage, and only he has the key.

Also, this cold storage is behind a freezer Zhang Xiao just inspected, with a separate entrance and exit, relatively secluded.

Zhao Wenjun’s transportation of fruits was also through his own truck, conveniently allowing for the transport of a body.

Criminal Investigation Team.

Ren Qiang nodded heavily: "Found it, in a cold storage by the Bailan River."

"Zhang Xiao found suspicious traces of blood inside, Lu Chuan went to the scene and found large areas of cleaned bloodstains with a fluorescent lamp."

"Lu Chuan’s bloodstain identification there has just been completed, confirming it is human bloodstains."

All mammalian blood is red and contains hemoglobin components.

Because hemoglobin is the physical carrier for blood-transported oxygen, blood appears red.

However, the components of hemoglobin differ subtly among species.

Through experimentation, the crime scene investigation can detect these differences and, by comparing with standard composition tables, determine which animal left the bloodstains.

"Can the bloodstains be confirmed as the deceased’s?"

"Not yet," Ren Qiang shook his head.

Lu Chuan has the analysis capability for bloodstain identification, but cannot determine ownership from inactive or even erased bloodstains.

Moreover, the cadaver, being severely decomposed, has long lost its blood, making it impossible to extract valid marker information.

Judicial comparison is even less feasible.

"However, I suggest investigating Zhao Wenjun now and even summoning him for questioning."

A decomposed body was found by the Bailan River, probably refrigerated, and large bloodstains were discovered in Zhao Wenjun’s leased cold storage.

With these findings connected, Zhao Wenjun certainly has the possibility of being the perpetrator.

"Moreover, when the cold storage manager called Zhao Wenjun saying police were going to inspect, there was a two- or three-second pause in his response."

During that call, Zhang Xiao requested the manager to use speakerphone.

"He said it was because he entered an elevator, and the signal wasn’t good."

"But Zhang Xiao clearly heard car honking sounds on the phone."

"Initially, Zhang Xiao didn’t pay much attention, but after finding the bloodstains, Zhang Xiao thought that Zhao Wenjun was probably frightened, hence the hesitation and not speaking immediately."

Often cracking a case involves linking seemingly abnormal actions with clues to confirm a problem exists.

"Mm, immediately summon Zhao Wenjun, and conduct a thorough survey of his social relationships!"

With a target identified, the rest of the work gets a lot easier.

In less than a day, all information on Zhao Wenjun was laid out before Qin Yong.

Zhao Wenjun, male, thirty-eight years old, a local from Haizhou City, has been in the fruit business for a long time.

"Zhao Wenjun started his business ten years ago when durians suffered a reduced yield due to natural disasters, and the prices skyrocketed. A distant relative of his in Malaysia helped him order a large batch of durians from abroad. After bringing them back to the domestic market, Zhao Wenjun earned his first fortune."

"Since then, with substantial funds at his disposal, Zhao Wenjun became a top-tier fruit wholesaler in Haizhou City."

"This is also why Zhao Wenjun needs to lease cold storage to store expensive fruits."

"Because he’s involved in the fruit wholesale business, Zhao Wenjun’s social connections are fairly complex, and he knows a lot of people. However, a thorough review found nothing unusual."

All thirty-odd people under Ren Qiang were mobilized for an in-depth survey of Zhao Wenjun’s social connections.

Yet, from family to friends, and business partners in fruit wholesale, no one was found missing.

Qin Yong carefully reviewed the report in his hand, furrowing his brow.

The investigation results on Zhao Wenjun were somewhat unexpected for Qin Yong; this person could be described as very clean.

Even with money, he doesn’t have any bad habits, doesn’t smoke, and rarely drinks.

Not to mention gambling, as he doesn’t even play poker. His family relations are relatively harmonious, with no signs of extramarital affairs from Zhao Wenjun.

"How’s it going in the interrogation room?"

Just two hours ago, Zhao Wenjun was summoned from Tianzhou City back to Haizhou City.

Qin Yong personally called the Criminal Investigation Team in Tianzhou City, and they promptly found Zhao Wenjun.

Now, he was in the interrogation room.
